Evelyn Wright, Countess of Thuringia

Ellen Gwyn Evelyn Maria Julian Wright, Countess of Thuringia (née Ogilvie; 20 August 1727 – 16 November 1831), posthumously named as Judith Thuringia, was the founder and first Demon Slayer Commander of the Demon Slayers, which became the largest contiguous Demon Slaying Organization in history after her death. After founding the Demon Slayers and being proclaimed Führerin of the newly-founded organization (meaning "leader"), she launched several successful operations against the Demon Empire as a whole, namely among them the Siege of Obano Castle (where over sixty-hundred demons were slaughtered by the Demon Slayers).
